A large team of scientists has nearly completed the first map of the mantle under the tectonic plate that is colliding with the Pacific Northwest and putting Seattle, Portland and Vancouver at risk of the largest earthquakes and tsunamis in the world.

Although California Gov. Jerry Brown signed a bill last week to create a statewide earthquake early warning system, the United States is still behind the curve in embracing technology that has proven to save lives, lessen damage and speed recovery after a major quake.

The San Francisco Chronicle recently reported on the work of Richard M. Allen, Director of the UC Berkeley Seismological Laboratory, for helping to develop an early warning system that flashes imminent danger when a damaging earthquake is about to strike.
